Webbför 2 dagar sedan · The molecule is described as being linear. Three electron pairs around the central atom The simple cases of this would be BF 3 or BCl 3. Boron is in group 3, so starts off with 3 electrons. It is forming 3 bonds, adding another 3 electrons. There is no charge, so the total is 6 electrons - in 3 pairs. WebbThe shared electrons are counted with both the atoms due to which each atom in the resulting molecule gets an inert gas electron arrangement of 8 electrons (or 2-electrons) in the outermost shell eg : H 2 molecule.

Webb1 mars 2012 · The shape of a molecule affects how it interacts with other molecules and that in turn can give rise to all kinds of interesting phenomena. One important area is how drugs work in the body. Using this as an example, the drug – a molecule with a specific shape – will commonly interact with a larger molecule, such as a protein. WebbThe origin of life has previously been modeled by biological heat engines driven by thermal cycling, caused by suspension in convecting water. Here more complex heat engines are invoked to explain the origin of animals in the thermal gradient above a submarine hydrothermal vent.
